Abstract

An electronic component includes; a magnetic-body core having a plate-shaped portion and a core portion which extends from an upper surface of the plate-shaped portion; a winding wire which includes a wound portion wound by a rectangular wire into an Edgewise winding form and two non-wound portions extending from the wound portion to two distal ends, and the core portion is inserted through the wound portion; and a magnetic exterior body which covers at least the wound portion and the core portion. The two non-wound portions are respectively arranged along a bottom surface and at least one of the side surfaces of the plate-shaped portion. Parts of the two non-wound portions arranged along the bottom surface are electrodes.

Claims

1. An electronic component comprising:

a magnetic-body core that includes;

a plate-shaped portion having an upper surface, a bottom surface, and a plurality of side surfaces, and

a core portion extending from the upper surface of the plate-shaped portion;

a winding wire that includes a wound portion wound by a rectangular wire into an Edgewise winding form and first and second non-wound portions, the first and second non-wound portions extending from the wound portion to first and second distal ends, the core portion being inserted through the wound portion; and

a magnetic exterior body that covers at least the wound portion and the core portion,

wherein the first and second non-wound portions are respectively arranged along the bottom surface and at least one of the plurality of side surfaces of the plate-shaped portion, and

parts of the first and second non-wound portions arranged along the bottom surface of the plate-shaped portion are electrodes.

2. The electronic component according to claim 1,

wherein the plate-shaped portion and the core portion of the magnetic-body core are independent members which are combined together to form the magnetic-body core.

3. The electronic component according to claim 1,

wherein one of the first and second non-wound portions is arranged along a first one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and a second one of the plurality of side surfaces of the plate-shaped portion, and

wherein the first and second non-wound portions are bent so as to extend along a side surface of the electronic component while being exteriorly exposed relative to the magnetic exterior body.

4. The electronic component according to claim 1,

wherein the first and second non-wound portions are arranged along a first one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and a second one of the plurality of side surfaces of the plate-shaped portion.

5. The electronic component according to claim 4,

wherein the first and second distal ends of the first and second non-wound portions are proximate the second one of the plurality of side surface of the plate-shaped portion.

6. The electronic component according to claim 1,

wherein the first non-wound portion is arranged along a first one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and a second one of the plurality of side surfaces of the plate-shaped portion, and

the second non-wound portion is arranged along a third one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and the second one of the plurality of side surfaces of the plate-shaped portion.

7. The electronic component according to claim 6,

wherein the first and second distal ends of the first and second non-wound portions are proximate the second one of the plurality of side surfaces of the plate-shaped portion.

8. The electronic component according to anyone of claim 1,

wherein the first non-wound portion is arranged along a first one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and a second one of the plurality of side surfaces of the plate-shaped portion, and

the second non-wound portion is arranged along a third one of the plurality of side surfaces of the plate-shaped portion, the bottom surface of the plate-shaped portion, and the first one of the plurality of side surfaces of the plate-shaped portion.

9. The electronic component according to claim 8,

wherein the first distal end is positioned near the second one of the plurality of side surfaces of the plate-shaped portion, and

the second distal end is positioned near the first one of the plurality of side surfaces of the plate-shaped portion.

10. The electronic component according to claim 1,

wherein at least one of the first and second non-wound portions has a step between the winding wire portion and one of a plurality of side surfaces of the magnetic exterior body.

11. The electronic component according to claim 3,

wherein a first part of the first non-wound portion and a second part of the second non-wound portion span the same side surface of the magnetic exterior body and have equal lengths.

12. The electronic component according to claim 3,

wherein a first part of the first non-wound portion and a second part of the second non-wound portion span the same side surface of the magnetic exterior body and have unequal lengths.

13. The electronic component according to claim 3,

wherein a first part of the first non-wound portion and a second part of the second non-wound portion span different side surfaces of the magnetic exterior body and have equal lengths.
